I'm not a modifier of things, so If mine wasn't done, I wouldn't have changed much on the bike, short of comfort things, like risers and seat. I'm sure they are good right out of the box.

do agree.. got mine with the acro pipe and braided brake hoses and enduro stile front mudguard, still looking for a original mud guard though and a centre stand... realy think they dont need any alterations out te box..

It really sound like its running rich. Have you disassembled the carb and inspected everything? I just did mine and came up with a small list, mostly orings. But then I found this thread http://advrider.com/forums/showthread.php?t=528038 and talked to Derek on the phone. He walked me through the entire carb and had me look at the slide and slide guide in particular, which it seems wears out a bit quicker when the slide holes have been drilled. I lucked out, he's local to me so I drove up to his shop and he set me up with all the parts to rebuild it. I am planning to do a whole write up (I should look to see if this has been done already!) with pics and contribute it to the index.

Gentleman, I'm posting this here because this is the most recent thread with a similar problem....

Many of you are familiar with the work I have done recently....here it is:

....bike fires right up, runs very well, throttle response is much better.....but....when i stop for a traffic light, in first gear, clutch lever pulled in the bike idles at 1600rpm and after a few moments it just dies....

1. Clutch switch has been thrown out....wires soldered together and tucked somewhere under triple clamps....

2. Carb has been cleaned, mixture screw set to 2,25 turns out from full in - standard setup.

3. Drilled the holes on the carb slide to 3mm

4. Needle clip on third from top.

5. Carb went not pinched (the hose going to the back from the right side of the carb and ending in the region of airbox), when I blow air from the end of the hose I can hear fuel inside....

6. Bike runs well when in revs, shifts well, all seems well.....

7. Replaced the ignition coil - because of some other issue...spark's good.

has low miles with orginal front tre, wass crashed rewards in to pole sustaining rear wheel and swing arm damage needs other work but ran excellent when crashed ...has been sitting in my shop for last 3 years must sell

In cocnclusion I will keep the stripes but I will search a more discreet way to do it.
Cheers

It's a great big bright orange motorcycle - there's never going to be anything discreet about a 640 Adv. Do the tiger stripes! I reckon they look great. I may even steal your idea for my Enduro - it's been plain for too long.

Cheers

I have been reading through the clutch threads as mine has decided its sick, I have come across the advice to change three of the clutch springs to the rallye type to improve feel and bite.

I cannot find any fiches showing different specs for rallye springs, all part numbers are identical and specify 2.8 x 37mm. Does anybody know where to get these rallye springs or even what spec they are?

I had a search through all the modern variants of the LC4, the only one which runs a different spring is the 660 smc. It uses a 3.0 x 33.5mm, is this what people are using? It should also be noted that the smc uses a different pressure cap.
